5 State of New Jersey, have invented certain new and useful improvements in Window- Screens, of which the following is a specication.

rllhis invention relates to window screens, and has for its primary object to provide improvements in that type of screens wherein a roll of open mesh fabric is employed, and -which has one end fastened to the lower stile of a sliding sash whereby vthe fabric will be rolled and unro ed as the window is lowered and raised.

A further object of the invention is to provide a screen of this character which is constructed and arranged in such maner as to be adaptable to windows varying in width, the construction preventing entrance of dies, mosquitoes and other insects to the room.

A still further object of thel invention is to provide a screen device of this character which is capable of being readily attached to and detached from the sliding sash, and which operates to exert downward movement to the sash. y

A still further and particular object of the invention is to provide a roll screen of the above described character, which is of simple and inexpensive construction, which is composed of but few readily assembled parts, all so constructed and arranged as to prevent wear,` breakage or derangement of the same, which is proof against .becoming disordered, which isf positivev in operation, and which will prove thoroughly ecient in the attainment of the ends for whch it is designed.

With these objects in view, together with others which will appear as the description roceeds, the invention resides in the novel ormation, combination and arrangement of parts, all as will be describedv more fully hereinafter, illustrated 'in the accompanying gllrawings, and distinctly pointed out the aims,

'.lhe invention be best understood by reference to `the accompanying drawings, whereinz- Figure l 1s an interior elevation of a conventional form of window frame and sashes,

and illustrating the application of a roller screen embodying my invention;

Fig. 2 is a vertical sectional view taken through the frame and sashes;

Fig. 3 is an enlarged .longitudinal sectional view taken through the roller screen and housing therefor; and

Fig. A is a sectional view taken on line 4-4 of Fig. 3.v

Referring now more particularly to the drawing, 5 indicates a window frame of the usual Well known construction, having the sliding lower and upper sashes 6 and 7 respectively.

rlFhe housing for the roller screen is indicated generally at 8 and comprises a pair of telescopic tubular sections 9. Each of these sections is provided at one end with a head 10, in the form of an annular plate, having inwardly projecting perforated lugscr ears 11, which engage the inner periphery of the end of the adjacent tubular housing section, and through which suitable screws or rivets extend to secure the heads to said sections. lt will be understood that thev tubular sections 9 are of equal diameter with the heads 10, and each section is provided upon one side with an outwardly extending foot 12,.by means of which the same may be secured to the sill of the window frame. rlhe adjacent ends of the sections 9y forming theA housing snugly interiit, andare capable of sliding one within the other.

One side of each of the tubular members 9 is hinged at its lower end as at 13, the said hinged portion constituting a door, by means of which access to the interior of the housing may be readily had. The freeend of the door portion of the housing when the said door is closed, is spaced from the adjacent end of the fixed portion, whereby a slot or opening 14, coextensive with the housing, is provided.

Each of the heads 10 is provided with a stem or rod l5, the said stems being secured to the heads at the central portions thereof,

and extend inwardly and centrally of the housing. These stems are relatively short length, and each has rotatably mounted thereon, a telescopic tubular roll section 16. The innermost extremities of these sections are telescoped as shown in Fig. 3 of the drawings, and a connecting pin or screw 17 may be inserted throu h registering apertures 18 in the said sectlons to maintain the samel against sliding relative to eachother. Encircling each of the stems 15 is a torsional spring 19, one end of which is engaged through a suitable aperture at the free end of the stem, while the opposite end is secured to the adjacent tubular roll section 16.

The screen which is indicated at 20, is arranged in overlapping sections, one section being secured to each of the tubular roll sections 16. The extremity of the screen fabric of each width is attached or in any other preferred manner secured to the roll section 16, and is led therefrom out through the slot 14 in the housing 8, to be secured at its free end to the lower stile orvcross bar of the sliding sash 6. The outer extremity of the screen fabrics are edged with headings or ribs 21. These ribs are preferably formed of relatively thin metallic plates, bent and rebent upon themselves as shown in Fig. 2 to confine and firmly secure the fabric end to the same. Outwardly projecting perforated ears 22 are formed upon the said ribs, whereby the same may be secured to the window sash, tacks or nails being employed for this purpose. These headings are also bent or formed in such manner as to permit of telescopic connection with each other, whereby the width of the end of the screen fabric may be extended or contracted when required.

The inner faces of the window frame are equipped with vertically extending guides 23, the-same; operating to maintain the fabrie-2a;prgepjerly stretched across the window p ,vent bulging off the same.

vvv,.@wi-n'ding powerl ofv the springs 1'9 vvin thehousing is such as will be capable b'frotatingthe drum formed ofthe tubular sections 16 with suiiicient force to draw the sash 6 downwardly to closedposition, and to maintain the sash raised, a rack .and pawl arrangement is provided. The rack is indicatedat 25, and is secured to one of the vertical stiles of the sash, while the pawl, illustrated at 26, is secured to the window frame and is adapted to engage within the teeth of the rack. From this construction it is apparent that the pawl will operate to prevent downward movement of the window when it is desired to retain the same open.

sides. The said housing is then secured to the sill with its slot portion 14 in close proximity to the lower transverse bar or stile of the sash 6. The ends of the overlapping screening are then connected to the lower bar of the window sash, and the device is ready for operation. As the window is raised, the screening fabric is drawn through the slot 14 and across the space left open by the raising of the window. The guide stri s 23 at the frame sides prevent bulging o the screen fabric and also prevent insects ainin access to theroom around the e ges o the screen. The window is maintained in open position by the rack and pawl means 25-26. Upon releasing the pawl 26, the sash, by operation of the torsional springs 19, will wind the drum or roll sections 16 to spool the screen fabric, whereupon the window sash will be drawn to closed position.

It is obvious that minor changes in the details of construction, combination and arrangement of parts may be made without departing from the spirit of the invention or exceeding the scope of the claims.

What is claimed is:-

1. In a device of the class described, a pair of tubular telescopic sections, heads at the ends of said sections, stems projecting inwardly from said heads and centrally of said sections, drum sections each rotatably inountedat one end upon one of said stems and being telescopic at their opposite ends means for securing together said telescoped ends, a pair of springs, each secured at one of its ends to one of said stems, and at its opposite end to the correspondin r drum seotion, and fabrics secured to sai drum sections.
